"I recently had the privilege of having my basement crawlspace encapsulated (3-layer protection) by Groundworks and I am beyond thrilled with the results. The project included the installation of a sum pump, 75 feet of drainage line, drainage mat, insulation, and heavy-duty plastic, and after just a couple of days, the improvements have been remarkable. In the past, my basement was plagued by a stagnant pond-like odor, a constant temperature of 59 degrees, and uncomfortably high humidity. Now, thanks to the encapsulation, the odor is completely gone, the humidity has been cut in half, and even without the subfloor installed, the temperature has noticeably risen. It’s incredible how much of a difference the encapsulation has made already. I first encountered Groundworks at the Home Show in Denver, where their display of encapsulation systems stood out as the best of the show. Their products were clearly superior to the competitors, both in quality and appearance. After receiving multiple bids, all of which were similarly priced, we ultimately chose Groundworks—especially after seeing how they provided honest, straightforward information without using scare tactics to upsell additional products. What truly set this experience apart, however, was the exceptional leadership and professionalism of the job foreman, Guillermo Hernandez. From start to finish, Guillermo and his team exceeded my expectations. Guillermo was not only professional and knowledgeable but also incredibly attentive throughout the entire process. He kept us fully informed at all times, conducting daily walkthroughs to show us the progress and outline the plan for the following day. His communication and dedication to the project were top-notch. Guillermo’s crew—Memo, Lazaro, Ulises, and Diego—were equally impressive. They were all punctual, respectful, and hard-working, giving their best to every aspect of the job. Their attention to detail and insistence on perfection were evident, and their commitment to delivering quality results was remarkable. It was some of the most intense labor I’ve ever witnessed, and I’m grateful for their hard work. Overall, I’m extremely happy with the job done by Groundworks. The encapsulation has already made a huge difference in my basement’s environment, and I would highly recommend their services to anyone in need of this type of work. A special thank you to Guillermo and his crew for their professionalism, hard work, and dedication to excellence. I am attaching before, during and after pictures."

Common Causes of your Crawl Space Problems in Sioux City

Moisture and Humidity

Excess moisture in your crawl space can lead to mold growth, wood rot, and structural damage over time.

Groundwater Seepage

Poor drainage or leaking pipes can lead to standing water in your crawl space, potentially causing mold growth and compromising structural integrity.

Poor Ventilation

Open vents in your crawl space allow humid air to enter, leading to condensation, mold, and long-term moisture damage.

Pest Infestations

Damp or unsealed crawl spaces create an inviting environment for rodents, termites, and other pests, leading to structural damage and contamination.

Soil Settlement

Shifting soil beneath your home can lead to foundation settlement, causing sagging floors and damage to crawl space supports.

Foundation Cracks

Cracks in crawl space foundation walls allow water, pests, and unconditioned air to enter, causing moisture and structural issues.

High Energy Bills

Poorly sealed or damaged crawl spaces can increase heating and cooling costs due to energy loss.

Stack Effect

Damage in your crawl space allows mold and odors to spread into your home. Repairing the crawl space prevents this, improving your air quality and living environment.

Climate Conditions

Heavy rains or drought can shift the soil beneath your home, leading to sagging floors or structural damage in your crawl space. Repairing these issues restores stability and protects your home from further problems.
